Jani Nikula 7c838e2a9b drm/i915/edp: read edp display control registers unconditionally
Per my reading of the eDP spec, DP_DPCD_DISPLAY_CONTROL_CAPABLE bit in
DP_EDP_CONFIGURATION_CAP should be set if the eDP display control
registers starting at offset DP_EDP_DPCD_REV are "enabled". Currently we
check the bit before reading the registers, and DP_EDP_DPCD_REV is the
only way to detect eDP revision.

Turns out there are (likely buggy) displays that require eDP 1.4+
features, such as supported link rates and link rate select, but do not
have the bit set. Read the display control registers
unconditionally. They are supposed to read zero anyway if they are not
supported, so there should be no harm in this.

This fixes the referenced bug by enabling the eDP version check, and
thus reading of the supported link rates. The panel in question has 0 in
DP_MAX_LINK_RATE which is only supported in eDP 1.4+. Without the
supported link rates method we default to RBR which is insufficient for
the panel native mode. As a curiosity, the panel also has a bogus value
of 0x12 in DP_EDP_DPCD_REV, but that passes our check for >= DP_EDP_14
(which is 0x03).

Add the minimal amount of PSR tracking into the crtc state. This allows

want to kill off eventually.

Manasi Navare d7ba25bd9e drm/i915/edp: Get the Panel Power Off timestamp after panel is off
Kernel stores the time in jiffies at which the eDP panel is turned
off. This should be obtained after the panel is off (after the
wait_panel_off). When we next attempt to turn the panel on, we use the
difference between the timestamp at which we want to turn the panel on
and timestamp at which panel was turned off to ensure that this is equal
to panel power cycle delay and if not we wait for the remaining
time. Not waiting for the panel power cycle delay can cause the panel to
not turn on giving rise to AUX timeouts for the attempted AUX
transactions.

Ville Syrjälä 1a8ff6076e drm/i915: Reorganize .disable hooks for pre-DDI DP
Most of our DP encoder hooks are split into per-platform variants.
.disable() an exception, and thus it's a bit messy. Let's split it
up as well. We'll leave the common parts in a helper called by
each platform specific hook. Now each platform has mostly its own
hooks. Some hooks are still shared between vlv and chv, and between
g4x and ilk. None of the remaining shared hooks have any platform
checks in them however so duplicating them doesn't seem particularly
useful.

There is a subtle change on VLV/CHV where we now disable PSR before
audio, whereas before we disabled PSR after audio. That should be
totally fine, and PSR is disabled by default anyway. Jani also pointed
out to me that PSR + audio doesn't seem like a particularly realistic
combination.

Manasi Navare 5b2eff5916 drm/i915/edp: Increase T12 panel delay to 900 ms to fix DP AUX CH timeouts
This patch fixes the DP AUX CH timeouts observed during CI runs causing
CI Failures on a specific PCI device. This issue was fixed previously
by adding a quirk but looks like we need to increase this delay even more
in order to get rid all the DP AUX CH timeouts.

Rodrigo Vivi d509af6c85 drm/i915: decouple gen9 and gen10 dp signal levels.
Let's decouple bxt, glk and cnl dp signal levels
from other DDIs to avoid confusion.

No functional change. Only a reorg to avoid messing
with currently working DP signal levels when
moving voltage swing sequences around to match spec.

v2: ddi_signal_levels is also called from other ddi
    platforms, so don't remove IS_GEN9_BC check from
    skl_ddi_set_iboos. (Ville).

Jim Bride dc911f5bd8 drm/i915/edp: Allow alternate fixed mode for eDP if available.
Some fixed resolution panels actually support more than one mode,
with the only thing different being the refresh rate.  Having this
alternate mode available to us is desirable, because it allows us to
test PSR on panels whose setup time at the preferred mode is too long.
With this patch we allow the use of the alternate mode if it's
available and it was specifically requested.

Manasi Navare 140ef138db drm/i915/dp: Validate the compliance test link parameters
Validate the compliance test link parameters when the compliance
test dpcd registers are read. Also validate them in compute_config
before using them since the max values might have been reduced
due to link training fallback.

If either the link rate or lane count is invalid, we still bail
from using the test parameters since the combination would not work
and instead use the fallback values.

v2:
* Added commit message to explain why we still bail when either of
of the params is invalid (Ville Syrjala)
* Add reason for validating in the comment (Jani Nikula)

Manasi Navare c99a259b4b drm/i915/edp: Add a T12 panel delay quirk to fix DP AUX CH timeouts
This patch fixes the DP AUX CH timeouts observed during CI IGT
tests thus fixing the CI failures. This is done by adding a
quirk for a particular PCI device that requires the panel power
cycle delay (T12) to be set to 800ms which is 300msecs more than
the minimum value specified in the eDP spec. So a quirk is
implemented for that specific PCI device.

v4:
* Add Bugzilla links for FDO bugs in the commit message (Ville, Jani)
v3:
* Change some comments, specify the delay as 800 * 10 (Ville)
v2:
* Change the function and variable names to from PPS_T12_
to _T12 since it is a T12 delay (Clint)

Manasi Navare 770a17a571 drm/i915/dp: Fix the t11_t12 panel power cycle delay from VBT read
When we read the VBT t11_t12 value for panel power cycle delay,
it is a zero based value so we need to 100ms to that. And then it
needs to be multiplied by 10 to store it in 100usecs unit same as
SW VBT.

v3:
* Add it as part of series
v2:
* Change the VBT value instead of HW readout and pp div (Ville Syrjala)

Dave Airlie 305b9eddee Merge tag 'drm-intel-next-2017-06-19' of git://anongit.freedesktop.org/git/drm-intel into drm-next
Final pile of features for 4.13

New uabi:
- batch bo in first slot, for faster execbuf assembly in userspace
  (Chris Wilson)
- (sub)slice getparam, needed for mesa perf support (Robert Bragg)

First pile of patches for cnl/cfl support, maintained by Rodrigo but
with lots of contributions from others. Still incomplete since public
review still ongoing.

Features/refactoring:
- Make execbuf faster (Chris Wilson), a pile of series to make execbuf
  buffer handling have fewer passes, use less list walking, postpone
  more work to async workers and shuffle buffers less, all to make the
  common case much faster (in some cases at least).
- cold boot support for glk dsi (Madhav Chauhan)
- Clean up pipe A quirk and related old platform hacks (Ville)
- perf sampling support for kbl/glk (Lionel)
- perf cleanups (Robert Bragg)
- wire atomic state to backlight code, to avoid pipe lookup hacks
  (Maarten)
- reduce request waiting latency/overhead to remove the spinning and
  associated cpu cycle wasting (Chris)
- fix 90/270 rotation wm computation (Ville)
- new ddb allocation algo for skl (Kumar Mahesh)
- fix regression due to system suspend optimiazatino (Imre)
- the usual pile of small cleanups and refactors all over

GVT updates contained in this tag:
- optimization for per-VM mmio save/restore (Changbin)
- optimization for mmio hash table (Changbin)
- scheduler optimization with event (Ping)
- vGPU reset refinement (Fred)
- other misc refactor and cleanups, etc.

Rodrigo Vivi cf54ca8bc5 drm/i915/cnl: Implement voltage swing sequence.
This is an important part of the DDI initalization as well as
for changing the voltage during DisplayPort link training.

This new sequence for Cannonlake is more like Broxton style
but still with different registers, different table and
different steps.

v2: Do not write to DW4_GRP to avoid overwrite individual loadgen.
    Fix PORT_CL_DW5 SUS Clock Config set.
v3: As previous platforms use only eDP table if low voltage was
    requested.
v4: fix Werror:maybe uninitialized (Paulo)
v5: Rebase on top of dw2_swing_sel changes
    on previous patches.
v6: Using flexible SCALING_MODE_SEL(x).

Rodrigo Vivi 938361e7a5 drm/i915/cnp: Panel Power sequence changes for CNP PCH.
Panel Power sequences for CNP is similar to Broxton,
but with only one sequencer.

Main difference from SPT is that PP_DIVISOR was removed
and power cycle delay has been moved to PP_CONTROL.

v2: Add missed pp_div write, that is now part of PP_CONTROL[8:4]
    as on Broxton. (Found by DK)

v3: Improve commit message. (By DK)

Maarten Lankhorst 8f647a0148 drm/i915: Convert intel_dp properties to atomic, v2.
intel_dp supports 3 properties, scaling mode, broadcast rgb and
force_audio. intel_digital_connector handles the plumbing,
so we only have to hook this up in compute_config and init.

Changes since v1:
- Remove limited_color_range too, unused. (danvet)

Jani Nikula b31e85eda3 drm/i915: Detect USB-C specific dongles before reducing M and N
The Analogix 7737 DP to HDMI converter requires reduced M and N values
when to operate correctly at HBR2. We tried to reduce the M/N values for
all devices in commit 9a86cda07a ("drm/i915/dp: reduce link M/N
parameters"), but that regressed some other sinks. Detect this IC by its
OUI value of 0x0022B9 via the DPCD quirk list, and only reduce the M/N
values for that.

v3 by Jani: Rebased on the reworked DP quirk database

v4 by Jani: Improve commit message (Daniel)
